MACHINE FOR TIGHTENING THE BILGE-HOOPS UPON BARRELS.

SPECIFICATION forming part of Letters Patent No. 756,783, dated April 5, 1904.

Application filed August 31, 1903.

To all whom. t may concern.-

Beit known that we, THOMAS FLANERY and NELs WHITEHILL, both of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Machines for Tightening the Bilge Hoops upon Barrels, of which the following is a specication.

Our invention relates to barrel-making machinery, and particularly to that class employed in tightening bilge-hoops upon barrels; and the object of the invention is to provide a mechanism by means of which an attendant can by the manipulation of a single lever easily apply uniform pressure simultaneously to the bilge-hoops and quickly force them into their proper position upon the barrel.

A further object is to provide improved means for holding the barrel and revolving the same during the operation of forcing the hoops thereon.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a plan view of a bilge-hoop-tightening machine embodying our invention. Fig. 2 is an end elevation of the same. Fig. 3 is a front elevation of a portion of the machine. Fig. 4 is a longitudinal vertical section. Fig. 5 is a section of Fig. 4, showing the tightening rollers or sheaves in their operative position; and Fig. 6 is a similar view showing the sheaves raised away from the work.

In the drawings, ,2 represents a suitable frame having at each end a bracket 3, provided with bearings for a rock-shaft 4 and a fixed shaft or rod 5, that extends substantially parallel with said rock-shaft and in the rear of the same.

6 represents frames or beds provided with longitudinal grooves 7, V-shaped in cross-section, adapted to receive track-rails 8 and slide horizontally thereon. A shaft 9 is mounted Serial No. 171,351. (No model.)

vided with cranks 10, that are pivotally connected, respectively, by rods 11 with lugs 12, that depend from the under side of said frame 6. The rocking of the shaft 9 `will impart, therefore, a sliding movement to said frames either toward or from each other, according to the direction in which said shaft is moved. A crank 13 is provided on the end of said shaft, connected by links 14 with treadles 15 and 15, by means of which the said frames may be reciprocated. We prefer to provide turnbuckles 16 in the rods l1, by means of which the distance between the cranks 10 and the pivotal connection of the rods 11 with the frames 6 can be increased or diminished and the stroke of the frames regulated.

Mounted upon the frame 6 are brackets 17, having bearings 18 for shafts 19, whereon pulleys 20, connected by belts 20 with a suitable source of power, are secured. The shafts 19 have inner threaded ends 21 to enterthe threaded hubs 22 of heads or chucks 23, that are dished or saucer-shaped and adapted to engage the ends of a barrel and hold the same firmly during the operation of forcing the hoops thereon. We prefer to provide rings 24 on the heads 23, having inner beveled edges 25, that engage the barrel-chimes and hold the ends of the barrel firmly and aid in centering it between the chucks. A bed 26 is provided between the heads 23 and curved ,to conform to the shape of a barrel and provided with rsupports 27, that receive and support the barrel in position to be engaged by the gripping heads or chucks.

Loosely mounted upon the shaft 4 between collars 28 and 29 are yokes 30, having forked ends 31, that straddle the shaft 5 land are provided with set-screws 32, that are adjustable toward and from said shaft 5 and by means of which the vertical movement of said yoke is regulated. The forward ends 33 of said yokes overhang the middle of the machine and are pivotally connected to bell-cranks 34. Sheaves or pressure-wheels 35 are mounted on'one arm of each bell-crank and revolve in planes substantially at right angles to the plane of said revolving heads and engage the outer edge of the bilge-hoops and roll over the same as the barrel is revolved. The other arms of the bell-cranks 34 extend inwardly toward each other and are pivotally connected to the ends of a plate 36, which in turn is connected at a point intermediate to its ends by a link* 37 with a lug 38, depending from a collar 38', secured on the shaft 4 between the yokes 3Q. When the lug 38 is moved backward, the bell-cranks will be swung toward each other to press the sheaves against the bilge-hoops. The collars 28 are each provided with arms 39, which overhang the forked ends 3l of the yokes 30 and serve to raise said yokes when the shaft 4 is rocked in one direction. An operating-lever 40 is secured on the shaft 4, preferably nearone end above the treadle 15, and an arm 4l is provided at the opposite end of said shaft 4, and a weight 42 is adjustably secured on said arml and tends to hold the lever 40 and the yokes 30 in their elevated position.

The operation of the machine is as follows: A barrel having been placed upon the supports 27, the treadle l5 is depressed and the chucks or heads moved toward each other to grip the ends of the barrel and rapidly revolve it. The operator then grasping the lever 40 rocks the shaft 4 and draws down the forward ends of the yokes 30 to depress the bell-cranks suiciently to allow the sheaves 35 1- to engage the'bilge-hoops 4and press on the edges thereof and force them toward the center of the barrel. As the hoops move in on the barrel the operator will continue to press down on the lever 40 and rock the shaft 4, causing the bell-cranks to be oscillated and swinging the arms bearing the pressuresheaves toward each other, so that each bellcrank and its sheave will accommodate itself to the different positions of the bilge-hoops. The pressure on the hoops will be uniform `and simultaneous,` and each bilge-hoop will as the barrel is revolved be pressed or forced into lits proper position in very short space of time and with comparatively little eort on the part of the operator. Upon releasing the treadle 15 and depressing treadle 15 the chucks will be withdrawn from the barrel to allow its removal and the substitution of another, when the operation described will be repeated.

We claim as our invention- 1. The combination, with a suitable frame,
